Custom turbo exhaust

[jsdvtr]

Looking at whats needed to get a system made up,

2.5" stainless pipe but unsure how many metres needed?
Looking at getting this-

Silencer but what size, lenght to buy? Where from?

Rear box-

Or get a tip welded onto the system like this but unsure how loud it would be without the silencer on most backboxes-

why not just buy a race system made for the car?

might need modding to fit turbo manifold ect but would surely be cheaper than building a custom one.

Because a race sytem is 2", i need a 2.5".

[dannygti]

Are you making it yourself?

No, id be taking it too a local place that makes up exhausts probably.

[dannygti]

Well why don't you just let them sort it out? I doubt they'd be making much money on the material itself.. Then you don't have to worry about it :D

[Vtr_Cam]

Won't they have the materials ready ? Instead of you supplying?

[JoshB]

Just go straight to a custom exhaust place. Ultimately they should only charge the same as any other Saxo system, the pipe diameter shouldn't increase the price any.

[jsdvtr]

Will they do 2.5" systems though as i thought they may only do the basic size system like 2" or 2.25" but i was quoted £100 with supplying my own backbox. That is why i was going to get a silencer mid way in the system and maybe just get a tip on the end similar to how you have done yours danny.

[wicked-vtr]

They should have all sorts of diameters if there any good, my mate had a 4" diamiter turbo back one made for his skyline. Alternatively, buy a second hand btb?

Of course they will.

They won't just make systems for saxo's and alot of larger engined cars use more than 2/2.25"

[blackie_2k5]

any good exhaust place will stock pipes from 1" in increments of .25" all the way to 5".....if they dont then theyre not a good exhaust place tbf

[xsi16v]

Steer clear of the cheap nasty powerflow or ets systems. Poor material, crushed bends and cheap boxes. They also tend to use thick material thats mega heavy!!.

Ive just made a 3" system for my car. I worked out for all the tube, mandrel bends, 2 boxes and materials it was going to cost £250.

Instead i picked up a second hand (mint) sierra cosworth system for £60 off ebay. Chopped it up and made it fit my car. £20 back from all the left over scrap = a 3" mandrel system for £40 :D

[stevo1600]

As above, I took my car to power flow and in my personal experience, they are shit.

Look for a good exhaust place.

[jsdvtr]

Looking at getting the parts for this soon.

Going to see how many metres i will need of stainless pipe. Will use a centre box just after the downpipe but thinking of just using a 3inch exhaust tip at the end of the system without a box. Will this be ok, it will probably be abit load though. Using mandrell bends also.

Or other idea was use the miltek backbox i have atm and make up a system but would the original backbox be to restrictive?

The backbox will more than likely be restrictive. I now have the exact same dilemma, I was hoping to keep my existing backbox and just replace the 2" pipe with 2.5" but its looking like Im going to have to get a new backbox too.
Like you, was just thinking of just adding a tip to the end but unsure of this.....need help also! Where are you sourcing your mandrel bends from?

[Ross]

Lol so you've decided to ignore all the above advice then? ;)

Just take it to MIJ exhausts or something. Boom. Sorted. Any size, any mods, any boxes, any power requirements.

I want a proper system with mandrell bends rather than pipe just bent like most custom exhaust places.

I guess if its too loud with just a single box in the system and not having one at the rear, could maybe just put a extra one in.the system. I know dannygti had just a silencer in the system then just a straight pipe through to the end.

[blackie_2k5]

A good exhaust place will use mandrel bends

Local place near me does them for £300, turbo back... all mandrel bent and tig'd up with proper joints, centre and back silencer if wanted, and flexi

Where is that mate? I'll see if theres anywhere near me that does proper systems but only 2 places i know of do powerflow and other is the same type of exhausts just bent pipe.

[blackie_2k5]

Aas in Newcastle

Advanced automotive systems

Waiting list is long though haha... January is the next appointments at the min

MIJ offered to do Titch's for (iirc) £375. All mandrel bent, full system from downpipe back. If I were getting a new one, that's where I'd go.

[blackie_2k5]

Think a mate just paid about 280 for his

Took the Saxo there with a cituning Mani and turbo bolted on, the made a flange for the turbo, downpipe with flexi, full system with mid silencer and backbox, in 2.5", all Mandrel bent and nicely tig'd up

Looks mint

[Ross]

MIJ blackie? I've heard good things from some corsa boys, but titch didn't actually end up there and I've not changed exhausts yet (although it's on my hit list!).

[blackie_2k5]

No dude

Compant I posted above in Newcastle, their work is awesome, hence as of last week the next available appointments are January haha :fcuk:

[blackie_2k5]

Nothing to see here

Double post fail

[blackie_2k5]

thought id bump this with a link as was on phone the other day :y:

if anyone want a decent system..the 6 month waiting list speaks for itself

[tweeqd]

alot of major manufactures will do custom stuff

Janspeed made my system on the car in stainless and its a work of art
not very cheap though :panic:

[jsdvtr]

What would a btb be like on a engine running just over 300bhp roughly? Would it be to restrictive? Unsure if the bends are the same as mandrel or bent pipe like how powerflow systems are made.

Do want it to be no good after buying one. I would be getting the first part of the system changed to be 2.5 and have v band flange welded onto it.

[Ross]

What bore is the BTB's (I don't know about them). I presume they are mandrel bent (if they're not you're losing a LOT of flow). Anything not mandrel bent is costing 1/2" over whatever bore size the pipe is generally, so a 2.5" pipe on a regular compression bender is only 2" wide on the bend at BEST.

2.5" is fine for 300bhp. Restrictive on much more above that though.

[Andy_K]

Btb are mandrel bent. They are not cheap exhausts. Bore is 2.5" iirc

[Ross]

Btb are mandrel bent. They are not cheap exhausts. Bore is 2.5" iirc

get on it then :D

[jsdvtr]

The bends seemed like they wernt normal bends. Suppose most of the shelf decent systems will be mandrel bends as apposed to just bends.

So you reckon should go for one? It just worked out cheaper and supposed to be best sounding systems and backbox fits nicely in back bumper.

[blackie_2k5]

What I've always wondered about btb.. Is why some ppl say 2.25 and others say 2.5"


But more startlingly.. They're Oe fitment.. So surely the flange at the downpipe join is only 2"?

[Andy_K]

That's the only downfall thinking about it. Connection to mani is 2.25" to the cat, then steps up to 2.5".

I could measure I suppose to confirm

[moxy89]

Andy your correct, its a 2.25 to join to the manifold then steps up to the 2.5inch, fantastic exhuasts and can get them cheap i just got rid of mine for £160. Sounded awesome and the workman ship is second to none

[jsdvtr]

Seems to be the best thing to go for. Well id be getting the 2.25 part changed to 2.5 and v band flange changed to suit.

[martyno]

Your on your way to making your own exhaust if you do that. Kind of defeats the whole point of having an 'off the shelf' exhaust?

If you can pick up a cheap second hand one then go for it.!.

[jsdvtr]

Got a system sorted now anyway, tig welded, mandrel bends centre exit and no mods as was made to suit my down pipe.

[boz]

what size dia was that quote for blackie?
i was in there the other weekend, awesome place and they really do know their stuff, i know loads of lads that have had custom work done with them, they do way more than exhausts ;D.
my mate got hit with a 1200 quid bill, just dropped off his cav turbo and said, make me a 3" system and do all of the boost pipe work, quality is 2nd to none, im defo going there for mine, i was just expecting the price for a saxo system to be more than you said.

[blackie_2k5]

I got quoted about £300-350 a while ago for 2.5" turbo back.. That was without seeing it.. Would have got better price when I took it in

Mate got his made there few weeks back for bout £300 I think, 2.5" turbo back, he's on here.. If he sees this he'll give a better idea, his downpipe is for sale at the min ashes changed to dp mani and downpipe from cituning

I'll see if I can find a pic..

[blackie_2k5]

Pic is I there.. Can't steal the pic out as phone is being a cunt

sweet, that stuart bloke who runs it really knows his shit, im not sure if the kid that works for is on here, he used to have a saxo. i was going to use a kid not far from there, he is a wizz kid, some dude of nordic decent, made up loads of systems for people i know, works of art, any kind of fabrication and just did them in his own time, cheap enough, but he has moved :(, i thought the aas saxo system would be alot more, but im defo going to them ;D
aye get some snapsup if you can ;D. my system needs to be a bit different, i will explain at a later date ;D lol
